@Dennis-LaRock - My experience with the Atlas Switch controllers is to rip them off and replace them with a non coil based switch controller. They inevitably trip the power surge on my power supplies and I hate wiring them to AC...even when that AC is an AIU. I know that Z-Stuff has switch machines that a lot of modelers use. The other options, which I don't recommend, is to rip the workings out of Lionel Remote Command Switches or make your own (DC based) (I have done both of these btw.)
